More than 20 people have reportedly been arrested, following a series of raids by police and food safety officials investigating the recent horse meat scandal.
Police and veterinary investigators carried out pre-dawn raids in 11 regions around southern France.
French Consumer Affairs Minister Benoit Hamon said the operation stemmed from increased monitoring of the food industry, after a French meat processing firm was at the centre of a Europe-wide scandal earlier this year over mislabelled frozen meals containing horse meat instead of beef.
"These were horses that should have ended up at the knacker, and instead they ended up at the butcher," he said.
